<dd><p>
 Convert the integer or float value when writing to or when
reading from network byte order (big endian) to host byte
order.
</p></dd>

<dt><b>'N':</b></dt>
<dd><p>
 Convert the integer or float value when writing to
or when reading from Intel byte order (little endian) to host
byte order.
</p></dd>

<dt><b>'0-n':</b></dt>
<dd><p>
 Specify a repeat count for the
preceding qualifier, e.g., 'c5' means the same as 'ccccc' (and
requires therefore a tuple of 5 values) but 'A10' means a
string with a size of 10 bytes (and requires only one value).
</p></dd>
</dl>
<p>The modifiers 'n' and 'N' can also be used as first character in the
format string and set the default byte order. 'n', which means network byte
order, is the default byte order when nothing else is specified.
</p>
<p>For UDP connections the binary data must be transferred in one network packet
so that the size of the binary data must not be bigger than one network packet.
Usually this means it should be smaller than the MTU (maximum transfer unit)
of the interface, which is usually about 1500 bytes, but only 576 bytes are
guaranteed (1280 bytes for IPv6).
</p>
<p>The parameter <a href="#To"><i><code><span data-if="hdevelop" style="display:inline">To</span><span data-if="c" style="display:none">To</span><span data-if="cpp" style="display:none">To</span><span data-if="com" style="display:none">To</span><span data-if="dotnet" style="display:none">to</span><span data-if="python" style="display:none">to</span></code></i></a> should be left empty for socket connections that
are already bound (all TCP connections and bound UDP connections), but in
case of an unbound UDP connection it must be used to specify the IP
address or host name and port number of the communication partner.
